4 Claims. (Cl. 248-215) This invention relates to a support bracket. The invention relates more particularly to a support bracket for a ventilator fan assembly. The invention relates still more particularly to an easily attachable and detachable support bracket for a ventilator fan assembly for a casement type of window or the type of window in which the window projects outwardly to open.

' Most ventilator fan assemblies are easily mounted in a conventional ventilator assembly in which a window is slidable within a frame member. In such an application, the slidable window or ventilator is opened to such an extent that the ventilator fan assembly may be disposed within the opening, the fan assembly being firmly retained between the ventilator and ventilator frame by a clamping action as the ventilator is closed as far as possible with the ventilator fan assembly disposed within the ventilator opening. However, in a casement type of ventilator or the ventilator which projects outwardly to open, it has heretofore been impossible or impractical to employ the use of a ventilator fan assembly adjacent or within the ventilator opening. This is due to the fact that the ventilator fan assembly cannot be properly clamped by a closing action of the projecting ventilator.

. Hence, an object of this invention is to provide means by which a ventilator fan assembly can be easily and readily mounted in or adjacent an opening of a ventilator assembly in which the ventilator projects outwardly to open.

- Another object of this invention is to provide a support bracket which is adapted for use with any one of aplurality of types of ventilator screen and frame assemblies.

Another object of this invention is to provide a bracket for the support of a ventilator fan assembly, which bracket is adapted for use with any conventional portable ventilator fan assembly.

Another object of this invention is to provide a support bracket for a ventilator fan assembly which bracket maybe easily andreadily attached to or detached from a ventilator.

Another object of the invention is to provide such a support bracket which can be used with any conventional ventilator assembly.

Another object of the invention is to provide a support bracket for a ventilator fan assembly which support bracket is light in weight, sturdy, and which may be built at relatively low cost. Other objectsand advantages reside in the construction of parts, the combination thereof and the mode of operation, as will become more apparent from the following description.

In the drawings, Figure 1 is a front elevation View showing a support bracket of this assembly attached to a ventilator assembly and supporting a ventilator fan assembly.

Figure 2 is a section view taken substantially on line 2-2 of Figure 1.

Figure 3 is an enlarged front elevational view of a Patented June 30, 1959 support bracket of this invention attached to a ventilator assembly and having a ventilator fan assembly carried thereby.

Figure 4 is a section view taken substantially on line; 44 of Figure 3.

Referring to the drawing in detail, a support bracket 10 of this invention comprises a relatively thin body 11 having a vertical portion 12 and a horizontal portion 14 integrally attached one to the other. The body 11 is provided with ribs 16 on the front surface thereof. The vertical portion 12 has a projection 18 horizontally attached thereto at the upper end thereof and extending therefrom. The projection 18 is provided with a downwardly extending flange 20 at the end thereof. Disposed at the rearward side of the vertical portion 12 of the body 11 and in spaced relation therefrom is an abutment plate 24. The abutment plate 24 is attached to the vertical portion 12 by means of a leg portion 26 having a flange 28. The abutment plate 24 is also provided with a leg 30 parallel to the horizontal portion 14 and partially disposed at the lower side thereof. The flange 28 and the leg 30 may be attached to the portions 12 and 14 by any suitable means, preferably by welding or the like. The leg 30 extends slightly beyond the end of the horizontal portion 14 and is provided with a plurality of upwardly extending lugs 32 at the end thereof.

The abutment plate 24 is parallel to the flange 20 of the projection 18 and is in alignment therewith as clearly shown in Figure 4.

Figure 1 shows the portion of a projecting type of ventilator assembly 36 which may form part of the interior of a room. The ventilator assembly 36 has a ventilator frame 38 which carries a plurality of stationary glass window portions 40.

Also attached to the ventilator frame 38 is a conventional screen frame 42 which is secured to the ventilator frame 38 by any suitable means such as by means of a plurality of screws and washer units 44. The screen frame 42 is in abutting engagement with the ventilator frame 38 in a conventional manner and carries a meshed screen 46. Within the screen frame 42 is fixedly attached a rod 48, as shown in Figure 4, which aids in retaining the screen 46.

The projection 18 at the upper end of the vertical portion 12 of the body 11 is adapted to engage the upper surface of the screen frame 42 and to rest thereupon. The central portion of the conventional screen frame 42 attached to a ventilator frame 38 may be slightly bent outwardly in order that the flange 20 of the projection 18 may be slidably disposed intermediate the screen frame 42 and the ventilator frame 38 as shown in Figure 4.

The abutment plate 24 engages the screen 46 for retaining the vertical portion 12 in spaced relation from the screen 46. A ventilator fan assembly 50 provided with one fan or a plurality of fans may be supported by the support bracket 10. Preferably the ventilator fan assembly 50 is provided with a plurality of apertures or slots 52 as shown in Figures 1 and 4. The lugs 32 of the support bracket 10 are adapted to fit into and pass through the apertures or slots 52 for retaining the ventilator fan assembly 50.

The ventilator fan assembly 50 may be provided with a comparatively thin wall frame member 56 as shown in Figure 4 so that the thin wall frame member 56 may be disposed intermediate the horizontal portion 14 and the lugs 32 for retaining the ventilator fan assembly 50 in proper spaced relation from the screen 46, as shown in Figure 4. The fan assembly 50 may thus be supported adjacent the screen 46 and adjacent a ventilator opening in a ventilator assembly.

The side of a ventilator fan assembly 50 which faces the screen 46 may be easily and readily reversed so that air may be drawn into a room or forced from the room by reversal of the sides of the ventilator fan assembly. This reversal may be readily carried out by removing the fan assembly from the bracket in themanner as shown in Figure, 4, reversing the sides of the fan assembly, and again booking the fan assembly over-the lugs 32 by means ofthe apertures 52 in the wall frame member 56' of-the fan assembly 50.

It is thus understood that the support bracket of this invention provides means by which a ventilator fan assembly can be readily and easily attached in or adjacentthe opening in any conventional ventilator assembly.

Although the preferred embodiment of the device has been described, .it will be understood that withinathe purview of this invention (various changes may bemade in the form, ,details, proportion and arrangement .of parts, the combination Vthereof and mode .of operation, which generally stated consist in ,a device capable of carrying out the objects set forth, as disclosed and defined in the appended claims.
